Communication Unit for Digital Displacement sensor SC-HG1

Please check “Communication Unit for Digital Displacement sensor SC-HG1” which can connect digital displacement sensor controller as well.

Features
Sensor that diagnoses its own state. Featuring a self-monitoring function!

Self-monitoring function released by using the digital displacement sensor communication unit SC-HG1 in combination with digital displacement sensor HG-S series and HG-T series.

Ultra-slim

The ultra-slim unit with a thickness of 8 mm 0.315 in allows easy installation in a limited space such as the inside of equipment.

Wide-angle measurement

The belt-shaped laser beam with a measurement width of 10 mm 0.394 in is used for measurement of dimensions and positions.

Industry’s highest*1 measurement accuracy

The HG-T series boasts repeatability*2 of 1 μm 0.039 mil and offers the highest*1 measurement accuracy in the industry.

● Sampling cycle setting can be selected from two options.
Standard: 1 ms, High speed: 0.5 ms.
● Average count setting can be selected from 11 options.
1 time, 2 times, 4 times, 8 times, 16 times, 32 times, 64 times, 128 times, 256 times, 512 times, 1,024 times

*2 This is the P-P value of digital measurement value with half shading at the middle position of the installation distance.

Two types of sensor heads are available.

Two types of sensor heads, one with a standard type receiver and the other with a slim type receiver, are available.

Side view attachment is available (optional). [HG-T1010]

Side view attachment (optional) is available for the standard type sensor head HG-T1010. This attachment can bend the laser beam at a right angle to allow flexible installation of the sensor head.

* Two side view attachment units are required when using the attachment on both emitter and receiver.
* The slim type sensor head HG-T1110 cannot be mounted with the side view attachment.
* Be sure to confirm proper detection using actual equipment in advance when using the side view attachment.

■Application example:
Lithium-ion battery winding section

Use of the side view attachment enables the installation of the sensor head closer to the winding section than when a conventional sensor head is used, thus contributing to the improvement of winding accuracy.

Beam axis adjustment assist function

The standard type sensor head HG-T1010 indicates the direction of receiver displacement relative to the emitter on the controller’s display screen and with the beam axis adjustment indicators on the receiver in an easy-to-understand fashion.

* The slim type sensor head HG-T1110 displays the displacement information only on the
controller’s display section.

Automatic emitter / receiver cable recognition

The HG-T series automatically recognizes the positional relationship of the emitter and receiver connected to the sensor head connection cable at the time the controller is turned ON. This function eliminates the need for identifying the correct cables to connect to the emitter and receiver. Wiring can be completed by simply attaching the connectors to the emitter and receiver.

* The sensor head connection cable is branched into two cables on the sensor head connecting side, but the two cables can be connected interchangeably to the emitter and receiver.

Die-cast aluminum case

The sensor head case is made of light and strong die-cast aluminum. It minimizes measurement fluctuations due to temperature effects. The die-cast aluminum case does not easily become distorted in shape by tightening of mounting screws as compared to a resin case. It is highly resistant to deterioration due to ageing. This robust case helps prevent deviations of beam axis alignment.

IP67 protection

The HG-T series features a protection structure of IP67(IEC) so it can be used in a place where the product may be exposed to water or large amounts of dust.

IP67 protection

The HG-T series features a protection structure of IP67(IEC) so it can be used in a place where the product may be exposed to water or large amounts of dust.

* Note that if the beam emitting / receiving surfaces of the sensor head are adhered with water or dust, correct measurements become inaccurate.
* The sensor head is watertight, but the connectors are not structurally resistant to dust, water or corrosion. Therefore, the HG-T series cannot be submerged in water or placed under falling water for measurement operation. Be sure to use the product in an appropriate environment.

All-direction LCD

The high-contrast LCD provides sharp and clear indications and wide viewing angle..

Dual display for added indication flexibility (equipped with NAVI function)

The 2-line digital display simultaneously shows head measurement (measured value) and judgment value (calculated value).

Equipped with intuitive circle meter

Values between allowable maximum and minimum values are indicated in green. Values outside of the allowable range are indicated in orange. This provides at-a-glance understanding of the margin to the tolerance limits.

Six types of detection modes


User-specified edge detection mode
Two points can be arbitrarily specified from multiple edges of the measurement object to be used for measurement, and the distance between the two points is measured.
* This change will be applied from production in November 2020.

Industry’s First!*
Auto edge detection mode

Edge detection can be started from either the TOP or BOTTOM without registering the detection direction. This eliminates the need for checking the detection direction.
* As of January 2019, according to in-company survey

Edge detection mode

External form / width detection mode

Inside diameter / gap detection mode

Central position detection mode

Monitoring of effects caused by stains

Notifies when the detection performance decreases due to accumulated stains.

Checks the degree of contamination based on the amount of light of the reference waveform (considered as 100 %).

* The reference waveform can be confirmed by using a combination of the “HG-T Configuration Tool” USB-based PC setting software and USB communication unit SC-HG1-USB or RS-485 communication unit SC-HG1-485. For details, refer to “Software”

Stable measurement of even transparent workpieces

The judgment level can be adjusted according to the degree of transparency.

Elimination of effects caused by fine foreign matters

The judgment filter value can be adjusted for the prevention of erroneous detections due to fine foreign matters.
The judgment filter value can be set to a desired value between 3 and 50.

Increasing the filter value ignores values resulting from foreign matters.


Invalidates sudden changes in measurements

If there is a sudden change in the edge position of the work piece, the change is invalidated and the judgement value is stabilized.
* This change will be applied from production in November 2020.

The USB communication unit provides convenient functions that facilitate the setting of the HG-T series while observing the waveform of received light by operating the dedicated USB-based PC setting software. The USB-based PC setting software can be downloaded free from our website.

*1 When connected to the communication unit for digital displacement sensor, up to 14 slave units can be connected per master unit.
*2 Dependent on PC environment.
